SHEAF-BINDING HARVESTER.

SPECIFICATION forming part of Letters Patent No. 683,609, dated October 1, 1901.

Application filed February 20, 1900. Serial No. 5.910. (No model.)

To all whom it may concern.-

Be it known that I,JosEPH BISPHAM LEATH- ERBARROW, a citizen of the United States of America, residing at Manchester, in the county of Lancaster, England, have invented a new and useful Improved sheaf-Binding Harvester, of which the following is a specification.

This invention relates to an improved construction of sheaf-binding harvesters, with the object of improving the means for bundling and tying the sheaves and dispensing with the packers.

For the purpose of more clearly describing the nature of my invention I have annexed hereunto three sheets of drawings. In the several views shown therein similar characters refer to similar parts.

Figure 1 is a side view showing my invention applied to any ordinary reaping-machine. Fig. 2 is a plan view with the needle and tying mechanism omitted. Fig. 3 is an end view also without the needle and tying mechanism and showing the rod controlling the clutch for these mechanisms broken away and its guide omitted for the sake of clearness. Fig. 4c is an end view, Fig. 5 a side View, and Fig. 6 a plan, of a part of the machine showing the discharging arms and needle.

The improvement which forms the subject of this invention may be affixed to any reaping-machine, such as partly indicated at a, in which the grain after being cut falls onto the platform and is carried up between canvas elevatorsj',that are supported on rollers j.

In this my invention the grain passes from the elevator and is received on a cradle that is formed of a row semicircular arms I) when they are in the position shown by dotted lines in Fig. 1, said arms being fixed to a crossshaft 0, extending from side to side of the frame at and supported in brackets c. A lever e is fitted to one end of the shaft 0. At the inner end of this lever a balanceweight f or an equivalent is attached, and the opposite or outer end e is connected by a rod gto a lever 70, that is fitted on the end of a transverse shaft Z, which is placed above the shaft 0 and 50 parallel thereto. Arow of semicircular arms q are fitted on and depend from the shaft Z,

which is pivoted in brackets, as m. The needle p is carried by a shaft 29 in bearings on the frame 25, so that when encircling the sheaf the back of the needle is outward and the needle-eye p inward, or the reverse of the ordinary position. Any preferred form of knotter may be employed for binding the sheaf. The binder attachments employed in combination with the mechanism hereinabove described may be such as shown or has been in use hitherto.

In the construction shown in the drawings, co is the driving-wheel, from which power is transmitted to the binder attachments through the sprocket wheel a, chain (1 shaft o bevel-wheels d shaft a sprocketwheel 7" on the latter, and a chain to the sprocket-wheel a, fast on the shaft 8, which turns in the frame t. At the other end of this shaft 8 is a sprocket-wheel a loose on the shaft, but adapted to be clutched thereto by a clutch v when the latter is freed from the stop-bar u, pivoted to the frame d. When this bar is in the position indicated by the dotted lines in Fig. l, the catch 1; of the clutch comes against the end it of the bar and the clutch is held back, so that the sprocketwheel a is held free on the shaft. When, however, the stop-bar u is raised to the position shown by full lines in Fig. 1 and the clutch is thus released, the latter will clutch the wheel a to the shaft and then by means of a chain will transmit rotary motion to the sprocket-wheel a, fast on the crank-shaft 7, Figs. 1, 3, and 5. This shaft 7 has at its outer end a crank 10, connected by a rod 11 to a crank-pin p on the needle 1). Another crank 12 on the shaft 7 is connected by a rod 13 to an arm 00 Figs. 4 and 5; on a shaft as, carrying a pair of discharge-arms 0a.

In working my invention the inner end of the lever c, with the weight f, will be in the position indicated by dotted lines in Fig. 1, which will cause the cradle 19 also to be in the position so indicated. The lever 6, whose downward movement is limited by a stop 6 on the frame (1, passes through a slot 82111 the rod .9, whose upper end works in a guide 3, and the lower end of said rod is connected I00 to the'free end of the stop-bar u. The end it engages with the catch 41 of the clutch when the cradle 12 and the lever e are. in the positions hereinbefore named and prevents action of the clutch. When a supply of grain has been deposited in the cradle b having sufiicient weight to overcome the resistance of the weight f at the end of the lever e, the cradle b will be lowered to the position shown in full lines in Fig. 1 of the drawings. At the same time the opposite end e of the lever 6 will cause the shaft Z to rotate, and the guard q will be placed in proximity to the elevators, thereby temporarily preventing the grain passing onto the cradle b. The raising of the weighted end of the lever c withdraws the end u of the stop-bar u from the catch '12, thereby permitting the sprocket.- wheel a to revolve with its shaft and so to actuate the sprocket-wheel a causing the needle p to encircle the sheaf, which is then fastened by the knotter, and the needle is withdrawn. Then the arms a: discharge the sheaf from the cradle b, which then rises by the action of the weight for equivalent, the guard q is lifted, the end u of the stop-bar it engages with the catch Q), stopping the motion of the sprocket-wheels a and a and the operation herein before described is repeated.

I claim as my invention 1. Asheaf-bindingharvesterhavinganelevating means, a cradle pivoted below the discharge end thereof, a guard pivoted above, cranks and a connectingrod between the cradle and guard, a lever and weight f, a

catch it and means to operate it from the cradle, in combination with binding devices below the upper position of the cradle, clutchgears and cranks to operate said devices when the catch a is operated, upon the cradle taking up a position below the receiving position, as and for the purpose described.

2. In a sheaf-binding harvester, an elevating means, a cradle at the discharge end of the elevating means, a guard q, lever and crank connections between the cradle and the guard whereby the guard is adapted to be placed in position in front of the discharging means upon the withdrawal therefrom of the cradle for the purposes described, a catch operated by the withdrawal of the cradle and clutch mechanism controlled by the catch in combination with a train of gears and cranks, a needle pivoted at p and operated so that when the cradle is in its lowest position it will have its point inward, and a crank and rod connecting the needle to the gears, all adapted to be operated after the cradle has left the discharge end of the elevator and at rest when it has returned thereto, as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
